What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

/dev/random is a blocking device that will block read when the entropy pool is empty. You should use /dev/urandom instead.

But even /dev/urandom is cpu intensive, wich is not a good idea if you are testing data transfer speed. A better alternative should be:

dd if=/dev/zero of=bigfile bs=1024 count=102400

This is only cpu intensive when you generate the file. After that there is no more overhead except for the bandwidth consumed.

I have a small shell script that compares the downloaded checksum with one done on the generated file, then prints the results (either checksums match or they don't).
